Abstract: The present disclosure is directed to a light-signal communication receiver device including a photo-receiving diode configured to generate a current signal on a first node from a received light signal, a preamplifier configured to convert the current signal on the first node into a voltage signal on a second node, and a differential amplifier including a first input connected to the first node and a second input connected to a third node coupled to the second node via an adjustment circuit. The adjustment circuit is configured to offset the level of the voltage signal of the second node, on the third node, in a controlled manner by a control signal.

Abstract: An electronic system includes a first LC oscillator connected to a first general-purpose input/output (GPIO) circuit and a second LC oscillator connected to a second GPIO circuit. A threshold generator is coupled to an input of the comparator. A control circuit is configured to control a measurement phase comprising a first capture phase and a second capture phase. A microcontroller is coupled to the control circuit and a power management circuit is configured to switch-off the microcontroller following activation of the control circuit by the microcontroller. The control circuit is configured to control the application of an excitation signal to the each oscillator via the respective GPIO circuit, control the GPIO circuit so that oscillations of the oscillator are provided to the comparator, and count, based on an output of the comparator, a number of oscillations in the oscillator exceeding a threshold output by the threshold generator.

Abstract: A light sensor includes an integrated circuit chip and a boost DC/DC converter. The integrated circuit chip supports an array of pixels, each pixel including a SPAD. The boost DC/DC converter delivers to the SPADs a bias potential capable of placing the SPADs in Geiger mode. The boost DC/DC converter includes an inductive element, a first switch, a second switch, and a circuit for controlling on/off switching of the first switch. The inductive element and the first and second switches are arranged outside of the integrated circuit chip while the control circuit forms part of the integrated circuit chip.

Abstract: According to one aspect, an integrated circuit includes: an electronic module configured to generate a voltage at an output, and an electronic control circuit coupled to an output of the electronic module, the electronic control circuit comprising an emissive electronic component. The electronic control circuit is configured to cause the emissive electronic component to emit light radiation as a function of a value of the voltage at the output of the electronic module relative to a value of an operating voltage of the electronic module, and the operating voltage is specific thereto during normal operation of this electronic module. The light radiation emitted by the emissive electronic component is configured to diffuse to an outer face of the integrated circuit.

Abstract: An integrated circuit chip includes a front face having an electrical connection pad. An overmolded encapsulation block encapsulates the integrated circuit chip and includes a front layer at least partially covering a front face of the integrated circuit chip. A through-hole the encapsulation block is located above the electrical connection pad of the integrated circuit chip. A wall of the through-hole is covered with an inner metal layer that is joined to the front pad of the integrated circuit chip. A front metal layer covers a local zone of the front face of the front layer, with the front metal layer being joined to the inner metal layer to form an electrical connection. The inner metal layer and the front metal layer are attached or anchored to activated additive particles that are included in the material of the encapsulation block.
